In a drive unit for a series hybrid vehicle comprising a first electric motor for driving and a second electric motor for power generation, wherein a first cylindrical inner housing provided on the outer periphery of the stator of the first electric motor and a second cylindrical inner housing provided on the outer periphery of the stator of the second electric motor are each provided with a helical cooling passage on the respective outer peripheries, formed so as to surround the stator in helical fashion. The first electric motor and the second electric motor are housed in an outer housing such that the rotor axes are parallel, the helical cooling passages of the first electric motor and the second electric motor are connected in series via a connecting passage, and the coolant outlet of the helical cooling passage on the upstream side to which one end of the connecting passage is connected and the coolant inlet of the helical cooling passage on the downstream side to which the other end of the connecting passage is connected are arranged at the end portions on the same side in the direction of the rotor axis.
